I have the FM springs on Bilstein HD shocks instead of the OEM shocks.  I did that because it was recommended by FCM but to be truthful I don't think I should have bothered and should have just used the OEM Bilsteins.

The ride is a little stiffer, lower and handles nicer.  I added a FM front bar and kept the OEM rear and the handling is just right for me.

Larry, is the handling noticably better?? In other words, is it worth the 275 shipped?

anyone know what causes the problem i described? it feels like i'm going to be launched off the pavement! i have the GC lowered all the way down, maybe its not enough suspension travel? maybe i'm hitting the bumpstops and thats causing it to jump? or maybe the car is so light so it feels like the car jumps?

help? for anyone else considering this setup, help them too  afro

If you have them lowered all the way with stock bump stops you are probably slamming into the bump stops and get an abrupt stop in suspension travel.  I would suggest a few things.

First Miatas aren't designed to be slammed so start by raising the car.  A good way for checking ride height is to measure from the middle of the axle to the bottom of the lip of the fender.  That way the height is not dependant on the tire inflation from wheel to wheel.  The lowest I would go is 12.5" in the front and 13" in the rear.

If doesn't help I would call up FCM and ask him which of his bump stops he suggests for your application and try them.

I'm betting your too low and just raising the ride height will help.  I believe in function over looks and having the car slammed might look good but it's not going to ride good.

Ill go for the springs, anyone have experience with them on the bilsteins?

I've had the H&R Race Springs on the stock bilsteins for ~8000 daily driven miles now. No issues to speak of and the car feels much better in the corners. You'll definitely get your moneys worth in feedback and stability but of course theres the firmness to get used to. I got mine from tirerack for under 220 shipped. Theres been alot said about the H&Rs and FMs on this forum. They seem to be the most popular options for replacing just the stock springs.

Will springs give you a more noticable change in handling characteristics than a sway bar? I know all springs and sway bars are different, but overall which will be more noticable. I'm hitting my limit money wise. I've ordered the DP, ording the full FM intake. For now I have to choose one or the other for the suspension and looking for advice on which one first if not both: springs or sway bar. I don't autox or do track runs but do like spirited driving on the outer country roads.

If it were me I'd go springs first.

Look at the FM suspension packages and you'll see they don't do sways until Stage 2

I am running on stock springs and shocks, and recently put on a set of FM sways.  With the wide adjustability of the sways I was able to tweak the handling characteristics to my track driving style (slightly loose setup with the FM sways set full soft front and full stiff rear).  Plus the stiffer sways have greatly reduced body lean which was getting excessive on the track with the very sticky Toyo R888s I use, and reducing body lean has produced better corner speeds, I believe mostly because of eliminating likely camber changes I was getting with the excessive lean.  The bottom line for me is that my low mileage '04 MSM now runs quicker lap times and is actually easier to drive near and at the limit.  The stiffer sways did however stiffen up the ride noticably on the street when the road surface is a little bumpy.  Quite a nice handling improvement for the relatively low cost of a set of FM Sway bars (but I did run the cost up a fair bit by also buying the very nice FM end links).  If you do decide to go with FM sways, I recommend waiting until FM is shipping their new design rear bar that eliminates the bar moving laterally under heavy cornering on the track with sticky tires -- I had to cut small slots in the rear suspension members so I could fit collars on the bar next to the inside of the mounts to stop the bar shifting back and forth.

My recommendation, if you're only going to do one thing, is to do sways. Of course, if you have bad shocks, then fix the bad parts. The reason the Stage 1 kit is springs and shocks without sway bars is because a package of just sway bars doesn't make much sense.

All of our bars now are shipping with an anti-slide bend in them. While there was never any need to cut your subframe to make our bars work, there's no chance they'll slide now.

I wouldn't think that the shocks are bad because the car only has 22,000 mi. on it and it was driven by a retired couple before I purchased it.

Anyone prefer one brand of springs over another? Racing Beat, H & R, FM or Eibach?

On this site seem the preference is H&R and FM. There are a several threads here on both.

the H&R does seem to lower it a bit more than the FM..so if you're going for the more lowered look, I would go for the H&R. From pics that I've seen for the FM springs, it doesn't seem to have lowered it that much from factory. As far as in quality, I'm sure both are great, and you'll always have the support of FM. Personally, I think I will go with the H&R whenever I decide to do springs simply because I'm looking for a bit more drop than what FM offers.

On the other side, if you live somewhere with lots of speed bumps, bad curb cuts and bad roads I'd go for the FM for more road clearance.
